METALLIC SHEET ROOFING Filed Nov. 28, 1954 of the attaching extension or flange I6 is disposed at a right angle to the longitudinal axis of the bead or rib H and terminates at or is flush with the edge I9, while the rear end of the attaching extension or flange l6 projects rearwardly beyond the rear end of the shingle l0, terminating in a transverse edge 25, disposed at a right angle to the longitudinal axis of the rib or bead II. The function of the extension at the rear end of the attaching extension or flange H3 is to provide means whereby such rear extension of the attaching extension or flange may be passed beneath the forward end of the attaching extension or flange N5 of a companion shingle and will thus overlap therewith. The construction shown in Figures 1 to 4, inclusively, is preferred as no additional metal is lost in providing the overlapping extension of the attaching extension or flange, but the form shown in Figures 5 and 6 will necessitate the loss of the sheet metal, corresponding to the length of the overlapp ng extension. The opposite longitudinal edge of the shingle I0 is bent to provide a hollow rib or beadifi, projecting above the same, and having its lower edge 21 substantially flush with thelower surface of the shingle and spaced therefrom, for affording a passage 28. The lower or forward end of the bead 2G is cut away from the point 21 to the free edge of the bead or rib,

affording a diagonal edge 29.

Inassembling the shingles shown in Figures 1 to 4, inclusively, the lowermost or forward shingle III in one upstanding row is first placed upon the ,roof adjacent to the lower edge of the roof so that the shingle shall suitably project below this lower edge and may be properly attached to the lower edge. The attaching extension or flange l6 of the forward shingle is now attached or nailed to the roof. The next shingle ID in the same row is now placed above or rearwardly of the first shingle, with the tapered inner layer or extension 20 disposed in the forward position. The next companion shingle to be placed in position may be slightly transversely inclined, and

the upper or rear end of the bead 26 of the forward or lower shingle will be guided into the lower or forward'end of the bead 26 of the companion upper or rear shingle, by virtue of the diagonal edge 29. After the insertion has been started, the next upper or rear shingle is swung down to a flat position upon the upper or rear end of the forward shingle, and the tapered extension 20 is inserted into the rear end of the rib II. The upper or rear shingle is now moved forwardly, and the edge l9 will snugly engage the rear end of the forward rib ll of the forward shingle, and the outer portion of the bead or rib ll of the forward shingle will enter the slot 22, whilethe forward extension of the attaching extension or flange l6 of the upper shingle will be arranged upon and overlap the rear end of the attaching extension or flange I6 of the forward companion shingle. The rear shingle is now attached to the roof by nailing the extension or flange 16 to the same. It is thus seen that an exceedingly tight joint is effected between the ribs or beads l l of the assembled shingles.' Where the edge l9 engages the upper end of the rib ll of the forward shingle,'such line of engagement is covered or spanned by the extension 20, and the adjacent ends of the attaching extension or flanges l6 overlap, rendering it impossible for water to pass these extensions or flanges, and the slot 22 is closed by the outer portion of the bead'orribof the forward shingle,

,The next rear shingle in the second row is applied in a similar manner so that its forward end will overlap the rear end of the companion shingle in the same row, and the forward extension of its attaching extension or flange 16 will overlap the rear end of the attaching extension of the last forward shingle. The attaching extensions of these shingles are, of course, nailed or attached to the roof. In a similar manner each row of shingles is completed and any desired rows of shingles may be assembled. The row of shingles next to the end of the roof is cut off and bent over the end of the roof and nailed thereto. It is thus seen that the shingles are securely attached to the roof without the use of separate clips. As before stated, the ribs H coact with the assembled ribs or beads I l for providing a trough to conduct away any water which may possibly pass the assembled beads or ribs H. The particular advantage in my construction is that the attaching extensions or flanges I6 are permanently secured to the shingles and will, therefore, be readily nailed to the roof. Where detachable clips are used workmen frequently fail to use a suiiicient number of these clips, whereby the shingles are not securely attached to the roof.

The shingles shown in Figures 5 and 6 are assembled in a similar manner, and the ends of the attaching extensions or flanges overlap, the difference being that the extension of the attaching flange is carried at the rear end of the forward shingle, instead of at the forward end of the rear shingle.

It is to be understood that the forms of my invention herewith shown and described are to be taken as preferred examples of the same and that various changes in the shape, size and arrangement of parts may be resorted to without departing from the spirit of my invention or the scope of the subjoined claims.

Having thus described my invention, what I claim is:

1. A metallic shingle having its material at one longitudinal edge bent over the same for affording a longitudinal hollow bead, said bead having inner and outer layers and an inner longitudinal edge spaced from the upper surface of the shingle for affording a longitudinal passage, an attaching extension permanently secured to the outer layer and having its forward end foreshortened and spaced from the forward end of the shingle, said head having its outer layer near its forward end cut away for providing a transverse edge spaced rearwardly from the forward end of the shingle, said attaching extension projecting forwardly beyond said transverse edge, the inner layer projecting forwardly beyond the transverse edge of the upper layer for providing a bead extension, theforward projection of the attaching extension being separate from the bead extension, the rear end of said bead having a transverse edge, said shingle being provided at its opposite longitudinal edge with a hollow rib having a longitudinal passage.

2. A metallic shingle having its-material at one longitudinal edge bent over the same for affording a longitudinal hollow bead having inner and outer layers and an inner longitudinal edge spaced from the upper surface of the shingle for affording a longitudinal passage, an attaching extension permanently secured to the outer layer and having its forward end f-oreshortened and spaced from the forward end of the shingle, said bead having its outer layer near its forward end cut away for providing a transverse edge spaced rearwardly from the forward end of the shingle, the rear end of the bead having a transverse edge, the attaching extension projecting longitudinally beyond one end of the outer layer of the bead, the inner layer of the bead projecting forwardly beyond the transverse edge of the upper layer to provide a bead extension, said shingle being provided at its opposite longitudinal edge with a hollow rib having a longitudinal passage.

3. A metallic shingle having its material at one longitudinal edge bent over the same for affording a longitudinal hollow bead having inner and outer layers and an inner longitudinal edge spaced from the upper surface of the shingle for affording a longitudinal passage, an attaching extension permanently secured to the outer layer and having its forward end foreshortened and arranged at generally a right angle to the longitudinal axis of the bead and spaced from the forward end of the shingle, said bead having its outer layer near its forward end cut away for providing a transverse edge spaced rearwardly from the forward end of the shingle and disposed generally at a right angle to the longitudinal axis of the head, said attaching exten sion projecting forwardly beyond said transverse edge, the inner layer of the bead projecting forwardly beyond the transverse edge of v the upper layer to provide a bead extension, said projection of the attaching extension being spaced from the bead extension for providing a being provided at its opposite longitudinal edge with a hollow rib having a longitudinal passage.

4. A metallic shingle having its material at one longitudinal edge bent over the same for affording a longitudinal hollow bead having inner and outer layers and a longitudinal passage, an at taching extension permanently secured to the outer layer and having its forward end foreshortened and arranged at a point spaced from the forward end of the shingle, said bead having its outer layer near its forward end cut away for providing a transverse edge spaced rearwardly fromthe forward end of the shingle and disposed generally at a right angleto the'longitudinal axis of the bead, said attaching extension projecting longitudinally at its rear end beyond the bead, the inner layer of the bead projecting forwardly beyond the transverse edge of the upv perlayer to provide a bead. extension, the rear,

end of said bead having a transverse edge disposed generallyata right angle to the longitudinal axis of the bead, said shingle being provided at its opposite longitudinal edge witha hollow rib having a longitudinal passage.
